3 Claims. (Cl. 25g- 108) This invention relates to heating systems, particularly of the hot water type wherein heated water is circulated through radiators or the like, and in particular, a motor driven perforated cylinder adapted to be inserted in a fitting of a water pipe for agitating the water and thereby causing circulation of B. t. u.s.

The purpose of this invention is to provide a circulator for hot and cold liquids in which the circulation of the liquid is a result of spinning a vertically positioned perforated cylinder in water or other fluid in a tube.

Various types of devices have been provided for agitating and circulating liquids particularly in heating and cooling systems, however, for certain installations it has been found advantageous to agitate the liquids instead of using a conventional pump for circulation whereby in agitating the liquids circulation of B. t. u.s is obtained.

With this thought in mind, this invention contemplates a motor having a small housing with radially disposed arms suspended therefrom wherein the motor shaft is extended through the housing and with a perforated cylinder carried by the motor shaft and adapted to be positioned in a liquid-carrying pipe or tube with the lower end of the housing threaded into a fitting positioned in the pipe or tube.

The object of this invention is, therefore, to provide means for inserting or mounting a perforated cylinder in a liquidacarrying tube whereby rotation of the cylinder extended therefrom results in circulation of fluids through the tube.

Another object of the invention is to provide an agitating device for causing the circulation of fluids in a tube in which the device may readily be installed in a fitting positioned in the tube.

Another important object of the invention is to provide means for mounting a perforated cylinder in a tube for circulating a liquid in the tube in which the device is adapted to be used for hot and cold liquids, the agitation of the device retarding freezing of liquids in tubes and p1pes.

A further object of the invention is to provide a device for agitating a liquid in a tube and thereby causing circulation of B. t. u.s in which the device is of a simple and economical construction.

With these and other objects and advantages in View, the invention embodies a tube having a T-fitting installed therein with a nipple threaded in the branch of the T, with a motor and housing therefor carried by the nipple and with a perforated cylinder and detlecting baille carried by the end of the motor shaft and positioned in the fitting of the tube.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure l is an elevational view illustrating the use of the agitating circulator, the device being positioned in a T at the intake end of a radiator, and the radiator being connected in a heating system.

Figure 2 is a side elevational view of the agitating circulator with the lower part of the device and also with a tube in which the device is positioned shown in section.

Figure 3 is a detail showing a sectional plan taken on line 3-3 of Figure 2 illustrating the connection of the nipple or tubular housing to the motor housing.

Figure 4 is a detail taken on line 4-4 of Figure 2 showing a vertical section through the perforated cylinder and baffle at the lower end of the motor shaft, the shaft being Ashown in elevation.

Referring now to the drawings wherein like reference characters Idenote corresponding parts, the improved agitating circulator of this invention, includes a perforated cylinder V10 having a baflie 11 at the upper end and secured on the lower end of a vertically disposed motor shaft 12 with a Aset vscrew 13, a nipple 14 providing a housing and having a packing gland 15 in the upper end and a bracket 16 secured to a motor 17 with screws 18 and in the lower end of which the nipple 14 is threaded.

As Villustrated in Figure .2, the nipple 14 provides the housing and with the lower end threaded into a branch connection 19 of a tting 20, such asa T, the cylinder 10 is `adapted to extend into an area between sections 21 and 22 of a tube whereby the cylinder is positioned in the path of a liquid passing through the tube. The section 21 is threaded into a hub 23 of the fitting 20 and the section 22 is threaded into a hub 24 at the opposite side of the fitting.

The cylinder 10 is provided with a hub 25 that is bored to receive the lower end of the shaft 12 and the hub is connected to the upper end of the cylinder with an inclined section 26. The shaft is provided with a collar 27 against the lower surface of which the baffle 11 and upper end of the hub of the cylinder 10 are held with the set screw 13 which is threaded in a section 28 in one side of the cylinder and which extends into a keyway or slot 29 in the lower end of the shaft.

The upper end of the nipple 14, which provides the housing, is formed with a plug 30 in which the packing gland is positioned, and a nut 31 having a shank 32 is threaded into the upper end of the plug to provide takeup means for the packing gland.

The upper end of the nipple 14 is threaded into a hub 33 forming the lower end of the bracket 16 and, as shown in Figures 2 and 3, the wall of the bracket terminates at the points 34 and 35 providing an open area 36 in one side. The Wall of the bracket is provided with screw driver bit receiving openings 37 and 38 by which the screws 18, which extend through a flange 39, are inserted and removed from the motor.

With the agitating device formed as illustrated, partic ularly in Figure 2, the agitator 10 is installed in the supply connection 40 of a radiator 41, the supply connection extending from a hot water tank 42 and the tank being connected to the radiator with a return connection 43. The supply connection may be provided with a valve 44 and a T 20 in which the agitating cylinder 10 is positioned is installed between the valve 44 and the radiator.

By this means liquid in pipe 40 or in a tube into which the perforated cylinder 1i) extends is agitated upon rotation of the cylinder and circulation is caused by B. t. u.s generated thereby. The baliie 11 prevents circulation of the liquid through the housing 14 to the packing gland thereby relieving the connecting parts of excessive pressure.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

l. An agitating circulator comprising a housing, a

bracket extended from one end of the housing, a motor carried by the bracket, said motor having a shaft, and said shaft extending through the housing, a perforated cylinder carried by the extended end of the shaft, a tube having a branch connection extended from one side and in which one end of the housing is positioned, said perforated cylinder being positioned in the tube, and a conical-shaped bale carried by the motor shaft and positioned in the branch connection and between the perforated cylinder and housing.

2. In an agitating device, the combination which com prises a nipple having threaded ends, a packing gland positioned in one end of the nipple, a bracket extended from the end of the nipple in which the packing gland is positioned, a motor carried by the bracket, a shaft extended from the motor through the packing gland and nipple, a tube having liquid therein, a T-ftting in said tube, and a perforated cylinder secured to the extended end of the shaft extended from the motor, the end of the nipple opposite to that in which the packing gland is positioned being threaded into a side connection of the fitting in the tube having a liquid therein whereby the perforated cylinder is positioned in the liquid and rotation of the perforated cylinder agitates the liquid.

3. In an agitator, the combination which comprises a nipple having threaded ends and providing a housing, a

packing gland positioned in one end of the nipple, a bracket extended from and threaded on the end of the nipple in which the packing gland is positioned, a motor mounted on the bracket, a shaft extended from the motor through the packing gland and nipple, a tube having a T therein, the end of the nipple opposite to that in which the packing gland is positioned being threaded into the T of the tube, a perforated cylinder carried by the extended end of the shaft and positioned in the tube, and a conicalshaped bafe mounted on the shaft and positioned between the perforated cylinder and nipple.
